=== Impact ===
According to ST, HID SMO8840 is for LIS2DH12. In Ubuntu kernel, support for this ID is missing in Bionic, and it's mapped to LNG2DM in D/E/F.

=== Fix ===
* e43d110cdc20 - iio: st_sensors: remap SMO8840 to LIS2DH12
This is in mainline kernel 5.6, and also 4.19, 5.4, and 5.5 stable trees.

=== Risk of Regression ===
Low.
Hans de Goede@redhat, who originally mapped SMO8840 to LNG2DM, confirmed the patch works for his Lenovo Ideapad Miix 320:

the bionic patch was included. Thank you!
